Sirs, Having read seemingly extensively on reconfiguring my core 3 kernel, I thought I would write a simple method for this list. However, I have got so far and hit a problem. Please can some one help. Kernel reconfiguration for Fedora Core 3. (AMD64 not sure this is relevant). Work within a terminal. su password vi /etc/sysconfig/kernel (Check that line beginning with UPGRADEDEFAULT ends in YES. If not, delete no and change to YES). mkdir /usr/src/redhat mkdir /usr/src/redhat/Build mkdir /usr/src/redhat/RPMS mkdir /usr/src/redhat/SOURCES mkdir /usr/src/redhat/SPECS (Obtain a src.rpm.kernel from either the source CD on via the internet by command: up2date --get-source kernel ). rpm -i /home/malcolm/kernel-2.6.9-1.667.src.rpm (Use your own path). cd /usr/src/redhat/SPEC rpmbuild -bp --target=/usr/src/redhat/SPECS/kernel-2.6.spec At this point all I get is 'syntax error'. After this point I hope to copy from old boot config to new kernel config and then use 'make xconfig' to enable missing hardware. Any comments will be appreciated and if successful other core 3 users may find some value here. With thanks. -- Malcolm Candlish <bm@xxxxxxxxxxxxxxxxxxxx>
